UP Langreo was founded on 4 July 1961, after the merge of local teams CP La Felguera and Racing de Sama, who both had a fiercy rivalry. The merge was made with the aim of overcoming from the rivalry between Sama and La Felguera not only in football, but in all areas.[1]
In its first season, Langreo achieved promotion to Segunda División, where it played during eight seasons out of the next ten years. Since its second relegation from Segunda to Tercera División, the club always played between Tercera and Segunda División B, the new third tier created in 1977, where UP Langreo played for the first time in its inaugural season.
